Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage drops below the specified threshold.
• The reset signal remains active for the timeout period after the voltage rises above the threshold.
• Low quiescent current consumption.

Advantages

• Ensures proper system initialization by generating a reset signal.
• Prevents data corruption or erratic behavior during power-up or power-down events.
• Wide supply voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• Low power consumption.

Disadvantages

• Fixed reset threshold voltage may not be suitable for all applications.
• Fixed reset timeout period may not be adjustable for specific requirements.

Working Principles

The ADM6321AY30ARJZ-R7 operates by continuously monitoring the power supply voltage. When the voltage falls below the specified threshold (3.0V), it generates a reset signal on the RESET pin. This signal remains active for the timeout period (140ms) after the voltage rises above the threshold. The IC ensures reliable system initialization and prevents data corruption or erratic behavior during power transitions.

Detailed Application Field Plans

The ADM6321AY30ARJZ-R7 is commonly used in various electronic systems where voltage monitoring and proper system initialization are critical. Some application fields include: - Microcontrollers and microprocessors - Embedded systems - Industrial control systems - Communication equipment - Power management circuits
